Organism Growth Influences Worksheet

Choose the best answer for each multiple-choice question. For the check-all question, select every correct choice. Use evidence from the data table when asked.

Genes and growing conditions

Organisms grow through interactions between inherited information and conditions around them.

1.Which characteristic is most directly influenced by an organism's inherited genes?

A cat's coat color
How much rain a garden receives
The amount of light reaching a plant
The number of predators in a habitat

2.Which condition is a factor around a plant that can affect its growth?

The plant's inherited DNA
The temperature around the plant
The genes passed down by its parents
The plant's chromosome number

3.Select all the factors around an organism that may influence its growth.

Water available to a plant
An animal's inherited DNA sequence
Nutrients in the soil
The temperature of the habitat

4.Two seedlings from the same species have similar inherited traits. One grows beside a sunny window and the other grows in a dim corner. The sunny-window seedling grows taller. Which explanation is best supported?

Different light conditions may have affected their growth.
The seedlings must belong to different species.
The dim-corner seedling must have more chromosomes.
The sunny-window seedling did not inherit genes.

Use evidence and explain

Use complete explanations where appropriate. In the data table, the mice in both groups had the same inherited genes and were kept under the same conditions except for diet.

Group

Diet

Average body mass

Higher protein

32 g

Lower protein

25 g

5.Using the values in the written data table, identify the factor the researcher changed, the outcome measured, and whether the results support an influence from conditions around the mice or from their inherited genes.

6.In two or three sentences, explain how both inherited genes and conditions during growth can contribute to a person's adult height. Include one example of each.

7.Complete this sentence with one word: A characteristic mainly passed from parents through genes is .

8.Complete this sentence with one word: A characteristic mainly shaped by conditions around an organism is .

9.Plan a simple investigation to test how the amount of water affects bean-plant growth. State a hypothesis, the factor you would change, the growth measure you would record, and one condition you would keep the same.
